I have cherished this Eliot quote for a long time. Time to make a note of it.

What we call the beginning is often the end
And to make an end is to make a beginning.
The end is where we start from.
We shall not cease from exploration
And the end of all our exploring
Will be to arrive where we started
And know the place for the first time.

–T.S. Eliot

The entire poem is Little Gidding, number four of “Four Quartets.”
